Abstract :
This paper identifies new class of network steganography methods that utilize mechanisms for handling oversized IP packets: IP fragmentation, PMTUD (path MTU discovery) and PLPMTUD (packetization layer path MTU discovery). In particular, for these mechanisms we propose two new steganographic methods and three extensions of existing ones. We present how mentioned mechanisms can be used to enable hidden communication for both versions of IP protocol: 4 and 6. Also the detection of the proposed methods is enclosed in this paper.
